    [ Upstream commit 11e94d2bcd88dea5d9ce99555b6b172f5232d3e2 ]
    
    Clang static analysis reports this issue
    d3.c:567:22: warning: The left operand of '>' is
      a garbage value
      if (seq.tkip.iv32 > cur_rx_iv32)
          ~~~~~~~~~~~~~ ^
    
    seq is never initialized. Call ieee80211_get_key_rx_seq() to
    initialize seq.
